Two-third of Leon's tropical fish in his tank is equal to one-fourth of harry's tropical fish in his tank Find the ratio of the no. Of Leon's tropical fish to the no. Of harry's tropical fish What fraction of the number of harry's tropical fish is the number of Leon's tropical fish

Answers

Answer:

L : H Ratio = 3 : 8  , L as a fraction of H = 3/8

Step-by-step explanation:

Let the no. of Leon's tropical fish be = L

Let the no. of Harry's tropical fish be = H

Given : 2/3 L = 1/4 H

L / H = 1/4 (3/2)

L : H = 3 : 8

Let total fishes or common ratio = x

L = 3/11  (x) , H = 8/11 (x)

Fraction L / H = [ 3/11 (x) ] / [ 8/11 (x) ]

L / H = 3/8

An 8-question true or false quiz is given to a class. If Lee guessed every question,
how many would she expect to be correct?

Answers

Answer:  4

Work Shown:

n = number of questions = 8

p = probability of getting a question correct = 1/2 = 0.5

n*p = number of questions we expect Lee to get correct

n*p = 8*0.5

n*p = 4

We expect Lee gets about 4 questions correct.

4 question that lee guessed would be correct.

There  8 question of true and false.
Lee guessed every question.

What is probability?

Probability can be defined as ratio of favorable outcomes to the sample of events.

Here,
Probability of guessing right answer = 1/2 = 0.5
Probability of lee guessing right answer out of 8 question.
= 0.5 x 8
= 4

Thus, 4 question that lee guessed would be correct.

8. Calculate the length of r or st

Answers

9514 1404 393

Answer:

  30 miles

Step-by-step explanation:

The Law of Sines is used for this purpose. The angle at R is the difference ...

  180° -(23° +34°) = 123°

Then the length r satisfies ...

  ST/sin(R) = RT/sin(S)

  ST/sin(123°) = (20 mi)/sin(34°)

  ST = (20 mi)sin(123°)/sin(34°) ≈ 30.00 mi

The length of r or ST is 30 miles.
